After walking to a depth of more than 3,000 meters, more than 60 layers of rock walked through, and the next few layers were also nothing, bare. www.biquge.info Chenhai was a little disappointed, and he was also a little puzzled, why there were petroglyphs on the top alone...

Chen Hai continued to swim downstream while thinking, saying that it was most appropriate to swim and walk. Chen Hai cast the Five Elements Spell, the water pressure was directly ignored, and he seemed to be as free in the water as if he was in the air, Chen Hai had long held his breath and relied on this true qi to maintain his body.

This giant pyramid under the sea is also a huge biosphere, like a giant island and reef, where countless marine life lives, because of its proximity to the tropics, so the temperature here is very suitable, and it will not be like the sea on the equator. Clownfish, parrot fish, wrasse, sharks......... All regard this place as an ideal habitat, in some places Chenhai even saw the existence of polyps, although small but still can't hide the spiritual power of Chenhai, with polyps here there is the foundation of coral reefs, it is estimated that there will be a huge coral reef in decades or hundreds of years.

Without disturbing the creatures surrounding the reef, Tatsumi cleverly avoided them and walked down slowly, trying not to attract their attention.

Finally, at the time of nearly four thousand meters, I saw the familiar traces again, from a little trace, slowly gathered into a perfect picture, at a glance, you can feel the perfect breath, each stroke is evenly deepened, round and smooth...

This is the first petroglyph, the scene on it is different from the previous one, but it is still the same city, because the giant pyramid in the middle will not change, but it can be clearly seen that the scale of the city is not as large as the outline of the city on the top floor, although because the area of the wall is large, every house on it is also very large, but it can still be seen that the number is not much, that is, one-third of the top floor. The overall style is still similar to the one above.

Continuing to go down, there was still no light at all, jumping along the rocks, gently relying on the resistance of the sea water to the ground of the next layer, looking back, there was another huge petroglyph, slightly smaller than the previous one.

Another jump, landed, and saw a slightly smaller city, although it was a little smaller, but I could see the happy faces of prehistoric humans painted on the petroglyphs, and the corners of the mouth were upturned like modern humans, and the smile from the heart, smiles are common to creatures with higher intelligence, not to mention prehistoric humans.

One by one, separated by several kilometers, depicts the same city, the same pyramid, but the most different is not only the size of the city, but also the clothing of the people, and the size of some houses. The human clothes on it are very soft, and at first glance, they are full of the feeling of fluttering in the wind and flowing in the wind. As for the people below, it looks hard and original at first glance. The difference between the houses is in the level, the houses in the petroglyphs below are all one-story, while the upper ones are two or three storeys, scattered, and the drainage system is very advanced at a glance, which is obviously a sign of advanced civilization.

Chen Hai synthesized all the petroglyphs he had seen, and found that these petroglyphs had one thing in common, a very striking commonality, that is, in the center of every petroglyph city, there would be a person on the giant pyramid, a person overlooking all living beings, only the person on the top petroglyph was anxiously raising his head, and the rest were all benevolent.

Tatsumi speculated that this person was either the saint of the city or its monarch, but he didn't even know the true identity of the city.

However, Tatsumi already had a rough guess, but he still couldn't believe it, it was Lemuria, a legendary prehistoric civilization, which is said to be a great civilization that coexisted with Atlantis in the same era.

This civilization is full of mysteries, only legends exist, and there is very little information that has been passed down to this day, almost only knowing its time, its place, its name, as for customs, kingdoms, rise and fall are unknown.

Tatsumi never thought that the legend about Atlantis was fake, there was no wind and no waves, at least it existed, but Tatsumi didn't believe in those illusory and powerful powers. According to historical data, Atlantis was finally defeated in a war of aggression, and then gradually declined, that war of aggression was a war against Greece, how could a country with such a legendary strength be defeated by a medieval Greece?

The answer is definitely impossible, the only explanation is that those powerful strength legends are illusory constructions of later people, maybe Atlantis has the strength to surpass other countries, but it is certainly impossible to reach the current level of development, as long as there is no complete mechanized civilization, it is fair in hand-to-hand combat, and there is a lot of reliance on the individual's physical strength, strength, and the ideas of decision-makers.

If this is the case in Atlantis, then Lemuria of the same era will definitely not be strong, and a strong civilization will certainly not leave a trace in this world, even if it will be destroyed overnight......

But everything in front of him is not told to Chenhai like this, that majestic pyramid is simply not the result of human civilization, how can it be built without the national strength against the sky, and the city that can accommodate hundreds of millions of people, even now there are still high-rise buildings to appear super-large cities. I didn't expect that prehistoric civilization could build such a large city, accommodate an unimaginable number of people, and grasp it very well, which simply overturned the current expert theory, you must know that with the expansion of the region, the ability to control the needs is increasing geometrically.

But there is another contradiction, that is, since it has the strength to build pyramids up to several kilometers high, why basically all the buildings in the city are one-story bungalows, and the luxurious ones have a courtyard, and the almost ones are only a few square meters, which are obviously the residences of the people at the bottom of the society.

So many contradictions emerged in Chen Hai's mind at the same time, suddenly like a traffic jam in the capital, the congestion hurts, Chen Hai shook his head fiercely, leaving these doubts behind, it's still a little early to think about this, he hasn't even finished exploring the giant pyramid, let alone the bigger cities below.
